When Clarke MacArthur took the return pass from Erik Karlsson, in the final seconds of Monday’s game with the Washington Capitals’ net empty, he was thinking just one thing: Don’t miss. MacArthur thought Karlsson was going to take the freebie himself to close out the victory over the Capitals. Instead, the 23-year-old defenceman, knowing MacArthur hadn’t scored a goal in 10 games, passed the puck off to MacArthur. He put it in for his 12th. “It was one of those moments where it’s just so unselfish to make a pass like that,” said MacArthur, after Tuesday’s practice. “When he came over in the huddle (after the goal) he was like, ‘You needed a goal, right?’ “I was like ‘Yeah.’ “It was pretty cool that in a split second, I can give him the puck, he can beat two guys and then think to know that I haven’t scored in 10 games and throw it over like that, and all in one motion. “A pretty special play by him. It just shows what kind of a guy he is. It was just a real unselfish play.” MacArthur was feeling anxious when he got the return pass, though. After Karlsson passed up the easy one, it would have been embarrassing if he missed. “When he got it and took off, I was (thinking),’Just put that in the net,’” said MacArthur. “I was kind of skating up, I could see him trying to delay, and I was like, ‘Oh God, here we go.’ I’m surprised my stick didn’t break in half or something. “It’s always good to get one and hopefully that sparks me to get going again.” “He’s a great teammate. Obviously I’ve got to buy him dinner on the road as soon as we head out.”
